った。This type of magnetic head generally includes a head chip around which a coil is wound, a chip stand that supports the head chip by fixing a part of its lower end surface to a part of the upper end surface of the head chip.
The chip base is equipped with a printed circuit board on which two conductive wires are printed, which is fixed to the upper end surface of the chip base, and both ends of the coil wound around the head chip are extended as lead wires, and are attached to the hent chip in the vertical direction. It is brought to the upper end of the chip stand through a through hole extending therethrough, and is connected to the conductive wire on the printed circuit board by soldering. However, in conventional magnetic heads with such a structure, the lead wire connecting the coil and the conductor on the printed circuit board is routed from the bottom of the chip base through the through hole to the other side of the chip base. In addition to the length of the wiring, the wires are usually only about 30 μm in thickness, which has the disadvantage that they tend to break when the head is used or assembled. Also, because the lead wire is long,
If an attempt is made to automate the wiring work of the lead wires when assembling the magnetic head, there is a problem in that troubles are likely to occur and the suitability for automation of the entire magnetic head is reduced.

One end of the flexible printed circuit board is located below the chip stand and near the head chip, so that it is connected to the coil of the head chip by a lead wire. The lead wires connecting the flexible printed circuit board are short.
